This whole thing seems to be affecting you on a personal level, as if you were a journalist or staff member of NPM. What is your plight?

 

Not exactly sure as to how to manipulate a dynojet runfile, but ok.

If they were written in text, i would be skeptical. However, wouldnt you be skeptical as well when they make 260whp on a dyno then claim them to be crank #s later on? Just something to mull over. The documented proof is in their own results. Just have to scrutinize it a bit. However, fake may have been too harsh a term. Perhaps fudged would have been better.

I dont know much about Mike Kojima, I will have to look into it some before I say anything. I have heard that he graduated from MIT....thats about it.

 

and what would the motivation be to fudge it?

You use the 260whp as some sort of example...yet they came back and said they made a mistake... and looking at it those are pretty old articles. And as far as I can see it wasn't because someone called them on it..

You've been in the Nissan Community how long? and you've never heard of Mike Kojima? Ever Heard of Sport Compact Car mag? Just about every Nissan Article in it for the last 6 years was written by him or looked over by him by accuracy.. from reading his book he is a Automotive Engineer for Nissan as well.

fudge or fake, both are pretty strong claims with no evidence.. at least that other guy you mentioned went and asked. That's a lot more respectable then saying it and hiding where you feel safe..

 

Since 1999, and I dont read sport compact car. And now that I have looked around a bit, I see that he has written a book as well for honda/acura performance and is a cheif engineer at Nissan. Also, he heads up a colum called "revenge of the nerds" at NPM.

PS: can you point me to where they admitted in their magazine their #s were a mistake?

 

Few people here know anything about him, even I know very little. We've pretty much established our own isolated part of the world here on Maxima.org. Mainly because of the complete lack of outside help from the aftermarket. We've been so used to NOT getting any outside help that we still pretty much don't even bother to look much elsewhere from time to time. The only sorta famous Nissan people known around here are the ones who've actively participated on this site to help others and find ways to unlock the secrets hidden within these vehicles.
Overall we have a tight-knit group here and when we as a collective see someone else or some publication post results that don't jive with our own collective results we tend to call shenanigans pretty quickly.


No disrespect to Mike, but he has ever done anything useful for us we certainly haven't directly or indirectly seen it.

 

Doesn't even matter... I think I proved my point with several pieces of evidence

Maybe you should read some of them and find out on your own..that seems to be half the problem.


Funny how I have my plight question..you are called on and proven wrong on several things and you aren't questioned about a thing.. The pecking order is clear

I'll just go back sitting in the backround a listening and laughing without commenting..thanks for your time. Sorry to question the elite

 

So that's it? I ask you a FAIR and simple question and you now decide to run off like a scared little kid?



You've really earned my respect now.

 

It really does matter, because the crux of your argument depends on it. I have read the NPM articles, and have yet to see any meritorious information beyond that of any person with basic automotive knowlege. Also, find me anyone in this community who has an intake dyno (dynojet runfile required) with a 15whp gain and you can have my position. Also, how many years of experience would you say that you have with dynamometers?

When did I ever ask you about your plight?

 

Besides, we don't need to question E55 because we all know he's using a Honda HP calculator.

 

Just a thought, but maybe threads like this one are one of the reasons why you're so isolated.. You can't allow moderators to bash others and not expect some sort of response.

I mean come on... Fake is a strong word with no evidence. You have to agree. I doubt it would have been allowed on other forums for it's sladerous nature and seeing it come from a moderator multiples the problem..don't you think?

I think Mr Kojima has probably done more than you realize... There probably wouldn't be much of any aftermarket for any Nissan without his help... maybe not directly to Maxima.org but certainly indirectly.. but that's my opinion and it's only worth anything to me

 

hahaha okay... nice way to cut the tension


peace

 

Be careful or a mod bashing will come your way

 

So now scans aren't good enough? hahaha

seems like most of the dyno's over there are scans...that used to be good enough for you until proven wrong on it..

http://www.nissanperformancemag.com/...ages/dyno2.jpg

you're actually funny... when you pick up a motortrend mag do you ask for the dyno run file? hahaha

So they are running around faking this one too? hahahaha damn man...are they responsible for the Kennedy Assasination as well?

I have plenty of experieance with both DynoJets and DynoPacks.. but that's beside the point.. I already showed that you were wrong on the DynoPack... Now it's scans that aren't good enough.. I bet if given a Run File you would say it was hacked....lol...which is probably easy to do..any digital data can be minipulated.

 

I still want to know. What is your affiliation with NPM?

 

Okay here ya go, it does matter... Show me some solid proof and I will take back everything I said and go over there and call them on it...

Saying its an Excel File is not any sort of proof.. have anything better?

 

Well, if you want to see the conditions the run was made in, and what the altitude, baro, creation time, etc... were you'd need the runfile, wouldnt you?

Id never even looked at NPM until someone started linking to it. I had no need to...none of the articles were relevant to what I was doing. As for motortrend, r/t, c/d.....I read those for entertainment, thats it. They post manufacturer crank numbers....so your little quip misses the mark yet again.

If you know how to maniupluate Dynojet runfiles...I can send you a few. You just assume that Id call anything "fake" that isnt mine. Since you have so much "experience" go get an intake and do a before and after on a 248C then email the runfiles. Id love to see the 15whp.

 

I asked you where it was, so I could see it for myself. You seem to know all about it. So far, I have only read it in a couple of posts in this thread.

Where did I say the 260whp dyno is an excel file? for someone who tells the truth, you sure do avoid questions well.

 

Are you ever going to give up your dyno conspiracy theories?

 

maxedout04
since you obviously only joined to defend NPM, why not just say so. why do you dodge direct questions and play games? Can I get cliff notes on your hard facts? why would anyone come on here going to such lengths to argue and know so much about the magazine in question.

The only point was that bias is possible in advertisements. So don't get disappointed if you buy something and don't gain 20 hp.

anyway....
big bucks? yeah I have deer all around my house, but in case you haven't noticed, I may have the least mods on my car in our or any gen. I do this purely for the thrill of bannings I actually donated before becoming a mod, then lost privileges like the free drawing

I wasn't at all complaing about my work, just pointing out how many simply don't explore other forums.

okay let's figure out if intakes add any power

 

Um, does 93+ octane count as a mod? Cuz if not then I win that category.

 

Yes but since that isn't the same tank of gasoline the car came with from the factory.............

 

Octane rating may not count, but don't forget the Maxima.Org sticker does...

 

You're right! It improves the car's self-esteem, so it can run faster. Cause you know everytime you drive by windows on a building and admire yourself and the car in the reflection, the car is grinning fenderwell to fenderwell looking at its own reflection. Women notice the car smiling and smile back because I know they are not smiling at me.

 

Mike Kojima is the man when it comes to modding Nissans, I do know he knows more about SR20s than 99% of the world

 

Ive always been fond of the PR CAI. Thats just me. It was one of, if not the first CAI's for the 4th gen's to come out. Ive heard it on numerous 4th gens first hand and I love it. Granted I havent heard any of the others first hand, but thats just me.

 

ok who voted? can I hire someone to clean this thread of it's junk? I'll pay you the same I get paid....

 

I’m brand new to your site. This is my first post. I just installed a Berktechnology short ram intake kit. I thought my “before and after” performance results might be relevant to your poll.

I have a 2005 Maxima, 6-speed with 2,100 miles. Everything is still stock. My Berk intake arrived yesterday morning. Around 10:30 AM I ran some base tests. Temperature was 76 degrees. All tires were at 39 psi. I had a ½ tank of gas and did nothing to reduce my car’s weight. Traction control was off. With a hand held stop watch, I ran several 0-60 tests. My best time was 6.51 seconds. Most were 6.6 to 6.7 sec.

I had hoped for better, but realized the engine is not fully broken in. I also needed to improve my technique. I had a tough time controlling wheel spin off the line. My launches were terrible. With too much throttle or clutch, the tires spun spastically, and I stood still. With less power off the line, I could moderate wheel spin, but also spent too much time in the low rpms. It became very obvious that a good 0-60 time in my car was more a test of my driving technique than my engine’s power. With better traction, this car would be much quicker! I’ll argue that if I could double my engine’s power, I wouldn’t get to 30 mph any quicker. The engine already exceeds the tire’s limits.

In an effort to evaluate my intake and not my driving skills, I resorted to simpler test. I timed how long my car required to accelerate from 2000 rpms to 6000 rpms in second gear. (No wheel spin, no shifts, just engine.) I ran this test several times and consistently required 5.00 to 5.01 seconds.

Lastly, I tested my car’s highway mileage. On the interstate, I set the cruise at 70 mph, A/C off, windows up. At a specific mile marker, I reset my car’s mileage computer. After a three mile run, my car’s avg. mpg was 32.2.

After installing the intake, I returned to the exact roads to repeat the exact same tests. The temperature was now 82 degrees. Most of my 0-60 runs required only 6.4 to 6.5 seconds. (My best time was 6.28 seconds, but that was with an exceptional/lucky launch.) There was no question that the engine pulled harder in the upper rpms. I am very comfortable saying the intake took .2 seconds off my 0-60 time. Not bad! My second gear 2000-6000 rpm test showed similar improvement. My times ranged between 4.85 to 4.87 seconds. (Down from 5.00 to 5.01).

Lastly, my highway mileage improved. On the exact same strip of highway, at exactly 70 mph, I got 34.5 mpg. I went back and ran that test again. Second time I got 34.4 mpg. That’s over 2 mpg better on the highway. I realize that is not as good as the claim NISMO makes for their cold air intake, but this seems good to me.

If my average mileage improves just one mpg, from 23mpg to 24 mpg, and gas stays at $3.00 per gallon, the intake will pay for itself in 31,307 miles. If gasoline stays at $3.50 per gallon, it will pay for itself in 26,813 miles. Based on my real life tests, the intake provides an admittedly small, but legitimate performance increase and improves gas mileage. I’m not complaining.

 

MDS, sounds like you did your best to test the Berk out. Very cool. I am still without an intake, only have a K&N drop in filter. How does a Berk cost and does your car sound different?

 

The only thing left would be the poll after removing the posts from the dyno-conspiracy-theory nutjobs and those that replied to them.

 

Apollos2, Berk Tech recently reduced their price by $20. I paid $159.95 for the intake. That's with the APEXi air filter, not the K&N. The K&N will cost you less. But based on my research, avoid the K&N. It seems that our Maxima's MAF sensor is particularly sensitive to contaminants. It seems that given enough time, the oil in the K&N filter creates a film on the MAF sensor, which adversely affects it. If it needs to be replaced, some dealerships may not cover it under warranty because they claim it is directly related to the after market modification. Anyway, after shipping, my total cost was $167.95.

With regard to sound, it is kind of like Jekyll and Hyde. At half throttle and low rpm, the sound is practically the same, almost unnoticeable. However, with heavy throttle above 4500 rpm, the intake develops an angry hollow growl, very strong and aggressive. It reminds me of the sound an old muscle car makes when the secondaries on the four-barrel kick in. As the rpms get higher, both the pitch and intensity increase. I like the sound very much. I drive fast just to hear the engine.

However, at redline the sound volume is not overly loud. My previous car was an Acura RSX Type S with an Injen Short Ram. That car was very loud. My wife hated it. In comparison, this Maxima is very muted and, dare I say, tasteful.

 

Im very impressed with the thoroughness of your tests. It seems this is one of the more scientific tests. I used to tune my highly modified 1975 Honda Civic with Weber carb the same way. I would change jets and then do testing to see if any improvements. Ill be installing a cat back exhaust, which a lot of thise conspiracy people think doesnt work either. Lets see if I can put that to the test and determine if there is an improvement or not. My bet is that there will be noticable improvement, but you never know. I think the 2000-6000 rpm test is most accurate. Eliminates starting-off-the-line factor. The other factor is gas in the tank although im not sure if its significant enough. If you top off the tank for the before and after test, then that factor is eliminated. Air temp is significant too, but your after test was done when it was hotter, so it should have slowed down. Ill be interested to see how my test performs with cat back exhaust.

 

I miss having a q-jet.

 

I think a much cheaper way of seeing if these stupid intakes do anything is take two identical AT 6th gens, make one stock and one with whatever intake you want and see the results at the strip, or anywhere for that matter...I'd never pony up for a dyno, but if I knew someone with my exact car who believed in the intake THIS MUCH, Id want to give them a run (actually multiple runs) for their money. Does anyone think thats a good idea? I come from the stock is best school of thought on intakes, so if you are in the Buffalo, Ny area, have a 6th gen SE AT (thats Onyx) this would be a good idea IMO. Cuz seriously, its what happens on the street that matters most anyway right?

 

Why Onyx? I don't think that the color would matter. There has to be someone in your area that has a intake.

 

I don't think there is too much of a horsepower differerence between the intakes available for our car. I think the major differences is whether the filter is cold air vs. engine compartment air, water bypass vs. non-water bypass, and general build quality and thought. I have an AEM intake on my '05 max but it lacks the water bypass, but that is easily fixed by adding one for $50. The Injen intake seems to have quality issues with it's brackets. The Nismo intake for the Altima looks like a very compelling solution that included the water bypass valve and is a col air intake. Plus it can be had reasonably cheaper thean the others via E-Bay.

 

I was just kidding about the onyx thing...any color

 

what's wrong with the MAXIMA Nismo Intake? yes, we get nismo FINALLY (although me thinks it's exactly like the Alti version)

no you weren't. don't try to spare their feelings. black is known to be more areo-dynamic

 

Carbon fiber

 

No, you did not just say that!

 

Good morning. Did you get your winter tires yet?
